Unfortunately, there is no definitive treatment for hydranencephaly. Management of the condition typically focuses on the specific signs and symptoms present in the affected individual and is mostly supportive. Hydrocephalus (the buildup of too much cerebral spinal fluid in the brain) may be treated with a shunt (a surgically implanted tube that helps to drain fluid from the brain).

What is microhydranencephaly?
Microhydranencephaly is a developmental abnormality that affects the brain. Signs and symptoms may include extreme microcephaly, scalp rugae (a series of ridges), profound developmental delay and severe intellectual disability. Imaging studies of the brain generally reveal incomplete brain formation and severe hydrocephalus (accumulation of fluid in the brain). In most cases, the underlying cause is unknown. Rarely, the condition is caused by changes (mutations) in the NDE1gene and is inherited in an autosomal recessive manner. Treatment is based on the signs and symptoms present in each person.
